Build for the second use

When reviewing a product idea, imagine someone returning tomorrow. They already understand the promise. What can they get done now, and how easily can they pick up where they left off?
This question changes which details deserve time. The opening animation matters less than whether the previous project is easy to find. A clever empty state gives way to the ordinary experience of editing something that already exists.
Walk through a repeat task
Take a tool for preparing a weekly report. The first run might guide someone through choosing a source and arranging a few sections. On the next run, they probably want to reuse that structure with new information.
If every visit starts from scratch, the product keeps charging an introduction cost. A saved report, a clear date, and an obvious way to make the next version may be more valuable than another onboarding screen.
Write down one repeat task before adding another feature. Start from the state the user actually left behind. Include small interruptions: an unfinished edit, a missing source, a change of mind.
This is a useful design exercise, not proof that people will return. That still needs to be observed. But it gives the product a chance to be useful when they do. Attention is a design decision offers another way to inspect that everyday experience.
